SS6G7a How have environmental issues affected Canada?
2
Activating Strategy Look at the map to the left showing the natural resources found in Canada. With a seat partner, identify the type of environmental issues that Canada might experience.
3
Environmental Issues in Canada
Acid Rain Pollution of the Great Lakes Extraction & Use of Natural Resources
4
As we discuss the Environmental Issues in Canada, we will summarize the information on a graphic organizer.
5
Acid Rain What is acid rain?
6
Causes of Acid Rain in Canada
Polluted gases released into the air from: Emissions from power plants that burn fossil fuels Emissions from factories that process minerals mined in Canada Emissions from cars
7
Effects of Acid Rain in Canada
Polluted farmland Dying trees Dead plants and animals in lakes Damage to buildings and statues (especially made of granite, marble, and limestone) Lower profits for industries
8
Pollution of the Great Lakes
9
Pollution of the Great Lakes
Polluted by waste from industries, sewage treatment plants, and run-off (pesticides, fertilizers, oil, grease, salt from highways) Acid rain is killing the plants and fish U.S. and Canada are both working to control industry, change to gas powered stations instead of coal-powered, add lime to help neutralize the effects of acid rain
10
Distributed Summarizing
If you lived in Canada, identify ways in which you might be able to help reduce the amount of air pollution and acid rain in the environment.
11
Extraction & Use of Natural Resources
12
Extracting Minerals from the Canadian Shield
Minerals from the Canadian Shield are valuable exports and power many industries Extracting minerals can cause damage the environment: Toxic waste gets into the ground and water Plants and animals lose their place to live Emissions cause acid rain
13
Use of Rivers on the Canadian Shield
Rivers on the Canadian Shield produce hydroelectricity (electricity created by flowing water) Hydroelectricity has caused problems because of the creation of dams, reservoirs, and change in river flow. As a result, there is flooding, erosion, and animals lost their place to live and their source of food.
14
Extracting Timber from the Canadian Shield
Trees are harvested as timber to make wood and paper products Cutting down a lot of trees in the same area (clear-cutting) can cause flooding and erosion into rivers New trees can be planted but take many years to grow The government is trying to help by restoring damaged areas and setting aside land to be protected
15
Distributed Summarizing
Do you think the benefits of extracting Canada’s natural resources outweigh the harmful effects of extracting its natural resources? Why or why not? Share your thoughts with a partner.
16
Summarizing Strategy Select one of the following tasks to demonstrate your understanding of the environmental issues in Canada: Make a bumper sticker illustrating an environmental issue affecting Canada (must include at least one environmental concern and its causes not general statements such as Save Canada’s environment) Make a Recipe Card about environmental issues in Canada Write an editorial to a newspaper describing an environmental issue affecting Canada
